.SH NAME
volmgt_running \- return whether or not volume management is running
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lvolmgt\fR [ \fIlibrary\fR... ]
#include <volmgt.h>

\fBint\fR \fBvolmgt_running\fR(\fBvoid\fR);
.fi

.SH DESCRIPTION
.sp
.LP
This function is obsolete. The management of removable media by the Volume
Management feature, including \fBvold\fR, has been replaced by software that
supports the Hardware Abstraction Layer (HAL). Programmatic support for HAL is
through the HAL APIs, which are documented on the HAL web site. See
\fBhal\fR(7).
.sp
.LP
\fBvolmgt_running()\fR tells whether or not Volume Management is running.
.SH RETURN VALUES
.sp
.LP
\fBvolmgt_running()\fR always returns \fB0\fR indicating Volume Management (as
implemented by \fBvold\fR) is not running.
.SH ERRORS
.sp
.LP
\fBvolmgt_running()\fR will fail, returning \fB0\fR, if a \fBstat\fR(2) or
\fBopen\fR(2) of \fB/dev/volctl\fR fails, or if any of the following is true:
.sp
.ne 2
.na
\fB\fBENXIO\fR\fR

.RS 9n
Volume Management is not running.
.RE

.sp

.RS 9n
An interrupt signal was detected while checking to see if Volume Management was
running.

To see if Volume Management is running:

.sp
.in +2
.nf
\fBif (volmgt_running() != 0) {
        (void) printf("Volume Management is running\en");
} else {
        (void) printf("Volume Management is NOT running\en");
}\fR
